Rivers of Power - Laurence Smith ****

I've never been entirely convinced that geography is really a science, but if there was a book that was likely to do so, it's Rivers of Power. What's more, Laurence Smith manages to bring alive the importance of rivers to the Earth, but more particularly to humanity, with some excellent storytelling.

 The book starts with a nilometer, an ancient structure for measuring the height of the Nile - and the role the Nile has played in Egyptian culture. From here we open out to a whole host of rivers around the world. Rather than focus chapter by chapter on particular locales, Smith leaps from place to place, covering the roles of rivers in, say, wars or trade or climate change. In doing so, he manages to communicate his enthusiasm and a feeling of engagement that makes the book both approachable and enjoyable. There's always something new and different turning up - no one, surely, would expect, for example, a chapter to begin with a discussion of the superhero movie Black Panther, using the fictional nation of Wakanda as a lead into a section on Ethiopia.

 I was concerned that there wouldn't be much science in the book, but in practice there is a fair amount, both in the description of the geological mechanisms and in the scientific approach used in the investigations of rivers in the associated stories. I do think the blurb goes too far in saying 'our quest for mastery [of rivers] has spurred staggering advances in engineering, science and law' - I take the point about engineering and to some extent law, but I can't think of a single fundamental scientific discovery that is related to our quest for mastery of rivers.

 Because rivers are so personal, I was slightly disappointed there wasn't much mention of the UK, but this is a book that's very much about the world view. So we see a lot from the big rivers of the world and rather less from the smaller, more intimate rivers that have still had big parts to play in local lives. Even so, the book rarely disappoints.

 I can't say this book has totally converted me to the cause of geography - but as a one-off, it's certainly a recommended read.

Who Invented the Computer? – Ian Watson

Ian Watson is the author of  The Universal Machine  and featured in a recent  Four Way Interview . Saturday June 23 2012 was the centenary of the birth of Alan Turing, the troubled genius who invented the modern computer. Why though do so few people recognize his name and his great achievements? In 1936 English mathematician Alan Turing, published a paper,  On Computable Numbers, with an application to the Entscheidungsproblem . This became the foundation of computing. In it Turing presented a theoretical machine that could solve any problem that could be described by instructions encoded on a paper tape. A Turing Machine could calculate square roots, whilst another might solve Sudoku puzzles. Turing demonstrated you could construct a single  Universal Machine  that could simulate any Turing Machine. One machine solving any problem for which a program could be written – sound familiar? He’d invented the computer. Then,  computers  were peop...

The Star Book – Peter Grego ****

This attractive landscape format book combines an excellent introduction to the stars and basic astronomy with a set of star maps, plus in depth looks at some of the stars featured, with a  bonus section on the solar system. Amazon says it’s a hardback, but in fact it’s a paperback with a rather ingenious cover – you can’t tell from the photo, but the words ‘The Star Book’ are punched through as a series of holes that show the white paper of the next page beneath. Like many astronomy/space books, the cover lacks shelf appeal because it is mostly black, but at least there is some original thought here. Unlike many books in this format which tend to concentrate on the pictures, there is a good deal of excellent text by Peter Grego, so there was no feeling that you were only getting the star maps and star ‘biographies’, something these days much more suited to an iPad or smartphone app. Instead, the opening 30 or so pages give a very good introduction that would be valuable to ...

Ignorance: How it drives science – Stuart Firestein *****

This is a delightful little book that really gets you thinking. I stress the ‘little’ part not as a negative, but as a good thing. There is nothing worse than fat, bloated popular science books where the author feels they have to get 120,000 words to be taken seriously. This is the sort of book that can be read in a couple of hours – but you will get so much more out of it than one of those tedious doorstops. The premise underlying the book is in once sense extremely simple, yet is fundamental to an understanding of what science is and what scientists do. And it is an understanding that is totally at odds with the typical way science is portrayed both in university lectures and popular science books. As Stuart Firestein points out, what is important is not the facts, but rather the area of ignorance. The interesting part and the fundamental heart of science is not about what we know, but about what we don’t know and where we want to look next. Take this lovely quote: ‘Working ...
